Abstract

A cover window manufacturing apparatus includes a plurality of fixed plates, a plurality of moving plates, a plurality of molds and a driver. The plurality of fixed plates is layered and spaced apart at a distance from each other. The plurality of moving plates is layered, spaced apart at a distance from each other and respectively disposed under the plurality of fixed plates. A plurality of connection members integrally connects the plurality of moving plates with each other. The plurality of molds is respectively provided on the plurality of moving plates, and inner spaces for molding the cover window are respectively defined in the plurality of molds. The driver is coupled to one of the plurality of moving plates, and is configured to move the plurality of moving plates towards the plurality of fixed plates such that the plurality of molds are pressed to the plurality of fixed plates.

First claim

What is claimed is:

1. A method for manufacturing a cover window, comprising:
arranging a plurality of fixed plates and a plurality of moving plates in a heating member, wherein each of the plurality of fixed plates alternates with each of the plurality of moving plates;
arranging a plurality of molds, each comprising a lower side mold portion, and an upper side mold portion facing the lower side mold portion, on each of the plurality of moving plates,
interposing a flat cover window material respectively between facing lower and upper side mold portions of the plurality of molds;
heating the flat cover window material by operating the heating member; and
moving the plurality of moving plates together with the facing lower and upper side mold portions having the flat cover window therebetween, toward the plurality of fixed plates, respectively, to press the plurality of molds to the plurality of fixed plates.

2. The method for manufacturing the cover window of claim 1 , wherein
a location of the plurality of fixed plates in the heating member is constant, and
the moving the plurality of moving plates comprises operating a driver coupled to the plurality of moving plates and configured to lift or lower the plurality of moving plates.

3. The method for manufacturing the cover window of claim 1 , wherein
the lower side mold portion comprises one of a convex portion and a concave portion,
the upper side mold portion comprises the other one of the convex portion and the concave portion, and
the pressing of the plurality of molds to the plurality of the fixed plates by the moving the plurality of moving plates forms the cover window material comprising a flat portion and a curved portion.

4. The method for manufacturing the cover window of claim 1 , wherein the moving the plurality of moving plates toward the plurality of fixed plates alternated therewith, respectively, presses each mold among the plurality of molds to the plurality of fixed plates at substantially the same time.

5. The method for manufacturing the cover window of claim 1 , wherein the plurality of moving plates are integrally coupled by a plurality of connection members.

6. The method for manufacturing the cover window of claim 5 , wherein the plurality of connection members maintain a non-contact state with the plurality of fixed plates.
